V4L/DVB (4205): Merge tda9887 module into tuner.
Most uses a tda988[5/6/7] IF demodulator as part of the device.
Having this as a separate stuff makes harder to configure it, since there
are some tda9887 options that are tuner-dependent and should be bound into
tuner-types structures.
This patch merges tda9887 module into tuner. More work is required to make
tuner-types to properly use it.
